WARNING!
Danger from chemical residue
There is normally chemical residue in
the liquid end and on the housing after
operation. This chemical residue could
be hazardous to people.
– It is mandatory that the safety
information in the "Storage, trans‐
port and unpacking" chapter are
read before shipping or transport.
– Thoroughly clean the liquid end
and the housing of chemicals and
dirt. Adhere to the material safety
data sheet for the feed chemical.
WARNING!
Warning of hazardous feed chemical
Should a dangerous feed chemical be
used: it may escape from the hydraulic
components when working on the
pump, material failure or incorrect han‐
dling of the pump.
– Take appropriate protective meas‐
ures before working on the pump
(e.g. safety glasses, safety
gloves, ...). Adhere to the material
safety data sheet for the feed
chemical.
– Drain and flush the liquid end
before working on the pump.
CAUTION!
Warning of feed chemical spraying
around
Feed chemical can spray out of the
hydraulic components if they are
manipulated or opened due to pressure
in the liquid end and adjacent parts of
the system.
– Disconnect the pump from the
mains power supply and ensure
that it cannot be switched on again
by unauthorised persons.
– Depressurise the system before
commencing any work on
hydraulic parts.
Danger of damage to the device
Take into account the information in the
"Storage, transport and unpacking"
chapter if the system is decommis‐
sioned for a temporary period.
1. Disconnect the pump from the mains/
power supply.
2. De-pressurise the discharge line.
3. Drain the liquid end by turning the pump
upside down and allowing the feed
chemical to run out.
